Inventor: HASEGAWA SHINICHI
IPC: H01L21/205
Filed: 1979-07-02
Abstract: PURPOSE:To obtain an epitaxial film having less crystal defect by eliminating simultaneous change of the temperature of a monocrystalline substrate and a reaction gas composition and sufficiently accelerating the growing speed of a gradient layer. CONSTITUTION:The monocryastlline substrate of gallium arsenide, gallium phosphide or the like is set, for example, in a range of 900-970 deg.C to form the first epitaxial layer having 0 or 1 or mixed crystal ratio. Then, the substrate is abruptly decreased at its temperature to 760-870 deg.C to form the second epitaxial layer having the same mixed crystal ratio as that of the first epitaxial layer. Subsequently, the third epitaxial layer, that is, a gradient layer is grown while retaining the temperature of the substrate, and after the mixed crystal ratio reaches prescribed value, the fourth epitaxial layer, that is, an operational layer is grown. In this manner, the growing speed of the gradient layer is sufficiently accelerated without changing simultaneously the temperature of the substrate and the reaction gas composition, thereby obtaining an epitaxial layer having less crystal defects.

Abstract: PURPOSE:To reduce the initial preheating time of base metal and to improve the quality in the structure of weld beads stably in the stage of using the thick base metal by using a coated arc welding electrode by forming the diameter of the core wire in the forward end part of the welding electrode convergent. CONSTITUTION:It takes time in preheating thick base metal to the adequate welding temp. thereof and the arc does not stabilize during this time, thus blowholes and cracks are generated in weld beads and the structure of the beads is inferior in quality in the stage of welding said metal by using a coated arc welding electrode. The forward end part 11b of the core wire 11 of said welding electrode in this case is formed to the diameter convergent in a step part 11a. Since the part 11b has the smaller diameter, the current density therein is large in the stage of welding, hence penetration is faster. The base metal is preheated initially up to the welding temp. in a short time, the arc is stabilized in the earlier time and the weld beads have the better quality in structure.
